Mutations in the genetic code can occur when

1 answer:

6 0

Answer: Mutations in genetic code occurs when DNA is being duplicated.Any changes in the base pairs leads to mutations by trasition or transversion. Change in amino acid leads to change in sequence and thus, mutation. This si carried on to new generation, if it takes place in germ cells.

There are 3 possible genotypes: NN, MN, or MM. In a group of 500 people, the frequency of genotype NN is 40%. How many individua

Readme [11.4K]

235 are the Individual numbers that would expect to have the MN type of genotype.

There are two equations necessary according to Hardy-Weinberg Equilibrium:-

p + q = 1

p² + 2pq + q² = 1

Let,

NN= p

NM=2pq

MM=q

So, according to the question, the frequency of genotype NN is 40%

40% of 500 = $\frac{500*40}{100} = 200$ Numbers of individuals

Frequency of individuals p = $\frac{Numbers of individuals}{Total populations}$ = $\frac{200}{400} = 0.4$

Find p² by taking the square root of p.

√(p) = √(0.4)

= 0.632

So, pp + qq = 1

qq = 1 - pp = 1 - 0.63

q = 0.37

The allele frequencies in the population are known, now finding the frequency of heterozygous genotype.

By Multiplying 2 × p ×q to get heterozygous genotype

2pq = 2 × 0.63 × 0.37` = 0.47

2pq = 0.47

So, 2pq × total population = 0.47 × 500 = 235, NM genotype.
